Shift light Was looking to hook up my autometer pro shift lite (5340) from what I understand I hook 12v red and black and green feed wire to white wire on pcm pin #48 for tach feed but when I do I get nothing I'm told that once the pcm has been custom tuned or flashed you loose the signal from white wire...is there a n other way to hook this light up? Also have a lingenfelter lcn 2000 would it be possible to get a signal from the launch control box??
